(certificate verification in data connections, which keeps failing and consuming CPU on jailbroken phones)

is the reason for the battery draining

i tryed SAM but i did not work

now the fix is to downgrade to 4.0.1 becuz the (certificate verification in data connections, which keeps failing and consuming CPU on jailbroken phones)
is not in the iOS`s befor the 4.1

now my question is ? should i install the 4.0.2 and isnt the 4.0 , 4.0.1 , 4.0.2 very slow with the 3G ??

You've asked the same question in multiple threads here. You also have some of your facts wrong, all iOS 4.0.x are equally slow on the 3G. Use SAM and fix this properly on 4.1 or 4.2.1
